I had a one time anal exposure...

Hi Doctor,

I had a one time anal exposure, I was the one receiving. I was tested at 4 months (16 weeks) negative via blood test. My doctor told me that I should get tested again after 6 months even if I don't do anything. Many others say that with today's testing, 3 months is already accurate. What should I do? Please help me, I'm very worried and confused. What kind of people take longer than 3 months?

Welcome to e health forum.

As per CDC and WHO recommendations, any person who is suspected of being exposed to HIV should get HIV tests at least after 4 weeks post exposure.

In case the test is negative, repeat testing is recommended every 4 weeks upto 6 months.

But in cases of very low risk of HIV infection, testing at 12 weeks can be considered as conclusive, if your treating physician finds your chances of infection to be low. This would be assessed by proper assessment of your medical and sexual history.

In your case, chances of your test results turning positive is very less likely. This is due to the fact that it is very difficult to acquire HIV infection just by a single episode of anal intercourse. Repeated exposures over long durations with a infected individual is needed for infections to be actually transmitted. Hence you should relax for the time being. But you should still repeat the test at the end of 6 months, so that you can be completely sure about your own status with regarding to HIV.

I hope this helps.

I had one time anal sex, first i just put penis in my ass surface not inside and then he used condom. then i went to test. the antibody test was non reactive after one week and then i went for HIV RNA DNA test after 19 days from exposure. It was < 75 and < 1.88 which the normal range in the test paper is also this. I want to know first: what is this copies/ml it is RNA or DNA of virus? or it is RNA or DNA of my blood serum? If it is virus what does it mean? I am negative? I am so worried , please help. thank you
